All info is in Project_Kawaii_Log.txt so check that. If someone wants to make it better feel free to. I’m pretty busy so there not much time to learn modding for this game.
I’m the author of the old translation version (back from ~Sept 2018). Seeing this post I realized that I never created a thread for it here. Whoops. Anyway, about it being broken: The short version is that the Powers That Be decided to discontinue lua support. Which broke a lot of Japanese mods using lua. Like this one. That leaves you these options…
Rebuild the mod by converting the code from lua to C++. (I have no idea how, sorry.)
Use lispcoc’s branch of CDDA which manually re-adds lua.
Remove lua-dependent parts of the mod.
I did No.3 with the most recent version (May 20th, 2019) and merged it with my own translation, which you can download here:
Bear in mind this downgrades the mod mostly to a basic items and gear mod, since the store no longer functions in the absence of lua support.
